Seal jar

ABSTRACT

A seal jar is constituted by a jar body collocating with an inner jar inserted into the jar body and a lid. An annular protruding rim in stair shape is formed on the upper end edge of the inner jar, and an annular groove corresponding to the lower end of the protruding annular rim for fitting with a seal is formed on the side edge of the inner jar which is covered by the lid which has a seal on the lid edge. The inner jar is inserted in the jar body, and the seal fitted in the annular groove of the inner jar seals at the inner side of the jar body. The lid fits at the upper end of the annular protruding rim of the inner jar, and the seal fitted in the annular groove of the lid similarly seals at the inner side of the annular protruding rim.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a seal jar, particularly to a novel seal jarcapable of remarkably reducing total space taken by seal jar used,having more diversified collocation in use, and capable of increasingmore practical value in its total implementation thereof.

2. Brief Description of Prior Art

Water molecules contained in air often causes deterioration, decay oreven mildewing of food. As food, seasoning or additive is oftenimpossible to be used up at one time, how to preserve or keep thesestuffs fresh has become an important issue which needs to be settled bypeople. Usually only capacity of accommodation is usually emphasized oncontainer for receiving stuff and refrigerator is used to keep thingsfresh, but not all foods are suitable to be preserved in refrigerator.Therefore, a seal jar is proposed to separate the food from air, so asto prevent food from deteriorating, wetting or to keep food away fromattracting ant, cockroach and mouse.

Generally, common seal jar is constituted by a lid collocating with ajar body. An annular body is formed on the bottom face of the lid, andan annular groove is provided on the periphery of outer wall of theannular body for accommodating an annular seal ring. An air-vent hole isformed on the seal ring. As the seal ring is fixed on the bottom faceinside the annular groove, the seal ring can rest against the inner wallof the jar body so as to achieve hermetically sealing effect, when thelid is fitted to the jar body.

The above seal jar can achieve anticipated effect of accommodating andsealing stuff therein, but it is found in practical implementation thatthe seal jar has only single one accommodating space. Thus, a number ofseal jars have to be used when many kinds of food are to be accommodatedand sealed up. As each seal jar is constituted by a lid collocating witha jar body, total space required is relatively large in use.Furthermore, the collocation also looks monotone in its usage.Therefore, there is still space for improvement present in its totalimplementation.

In view of the above disadvantages, the inventor of this inventionproposes a seal jar according to the research and improvement conductedon conventional structure and its defects, based on profound experiencein R&D and manufacturing in relevant field, with a purpose to achievebetter performance value in its practical application thereof.

SUMMARY OF THE INVENTION

This invention relates to a seal jar which is essentially constituted bya jar body collocating with an inner jar and a lid. The inner jar can beinserted and fitted in the jar body. An annular protruding rim in stairshape is formed on the upper end edge of the inner jar, and an annulargroove corresponding to the lower end of the protruding annular rim forfitting with a seal is formed on the side edge of the inner jar. The lidcan cover and fit on the annular protruding rim of the inner jar.Similarly, an annular groove for fitting with a seal is formed on theside edge of the lid. The inner jar is inserted and fitted at the upperend of the jar body, and the seal fitted in the annular groove of theinner jar seals at the inner side of the jar body. The lid can cover andfit at the upper end of the annular protruding rim of the inner jar, andthe seal fitted in the annular groove of the lid similarly seals at theinner side of the annular protruding rim. Thus, a single seal jar havinga number of accommodation spaces is used such that there is no need touse a lot of seal jars in case there is a need to use a number ofaccommodation space to receive food or the other stuff. In this manner,total space taken by seal jar used can be remarkably reduced. Besides,the seal jar has more diversified collocation in use. It can increasemore practical value in its total implementation thereof.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The technical content, objects and effectiveness of the presentinvention will become more apparent by the detailed description of apreferred embodiment of the present invention in conjunction with theaccompanying drawings.

FIG. 1 is a perspective exploded view of the present invention. As shownin the figure, the seal jar of the present invention is constituted byajar body (1) collocating with an inner jar (2) and a lid (3).

The jar body (1) is formed with an accommodation space (11) in itsinterior, and the inner jar (2) can be put inside the jar body (1). Theinner jar (2) also has a receiving space (21) in its interior and isprovided with an annular protruding rim (22) in stair shape formed onthe upper end edge thereof. An annular groove (23), corresponding to thelower end of the annular protruding rim (22), for fitting with a seal(24) is formed on the side edge of the inner jar (2). A vent hole (241)is provided on the seal (24). The lid (3) can cover and fit on theannular protruding rim (22) of the inner jar (2). Similarly, an annulargroove (31) for inserting with a seal (32) is formed on the side edge ofthe lid (3), and a vent hole (321) is also provided on the seal (32).

With the above structure as shown in FIGS. 2 and 3 respectively showingan assembling sectional view and a partial enlarged assembled sectionalview of the present invention, the inner jar (2) is inserted and fittedat the upper end of the jar body (1), and the seal (24) fitted in theannular groove (23) of the inner jar body (2) seals at the inner side ofthe jar body (1). The lid (3) can cover and fit at the upper end of theannular protruding rim (22) of the inner jar (2), and the seal (32)fitted in the annular groove (31) of the lid (3) similarly seals at theinner side of the annular protruding rim (22).

When in use, the inner jar (2) on the jar body (1) can be opened firstso that food or any other stuff can be put and sealed inside theaccommodation space (11) of the jar body (1) as shown in FIG. 4 of aschematic view showing a using state of the present invention, or thelid (3) on the inner jar (2) can be opened so that food or the otherstuff can be put and sealed in the receiving space (21), as shown inFIG. 5 of a schematic view showing another using state of use of thepresent invention.

The above embodiment and drawings are not intended to limit thestructural aspect of the present invention. Appropriate variations ormodifications conducted by the person having ordinary skill in this artwithout departing from the spirit and features of the present inventionare regarded to be still within the scope of the invention.

Based on foregoing description, the seal jar of the present inventionhas the following advantages when comparing with conventional stuff:

1. This invention is essentially formed with an accommodation space inthe jar body and similarly a receiving space in the inner jar. The innerjar can cover on the upper end of the jar body and a seal is used toseal at the inner side of the jar body, while the lid can cover andfitted on the upper end of the annular protruding rim of the inner jarand a seal is used to seat at the inner side of the annular protrudingrim. Thus, a single seal jar having a number of accommodation spaces isused such that there is no need to use a lot of seal jars in case thereis a need to use a number of accommodation space to receive food or theother stuff. In this manner, total space taken by seal jar used can beremarkably reduced.

2. This invention is essentially formed with an accommodation space inthe jar body and similarly a receiving space in the inner jar. The innerjar can be cover and fitted on the upper end of the jar body, and thelid can be cover and fitted on the upper end of the inner jar. When theinner content, such as tea, accommodated within the jar body has fewremains and needs new stuff recharging, the few remains can be put intothe inner jar and new stuff can then be put and sealed in the jar bodyso as to avoid mixing of new and old stuff. Thus, it is convenient touse old stuff remained in the inner jar first when in need. In thismanner, the seal jar has more diversified collocation in use.

Summing up above, the embodiment of the present invention is surely ableto reach expected effectiveness in application, and the specificstructure disclosed herein is not only unprecedented in the samecategory of product but also not open to the public before application.
